SunZia, the largest renewable energy infrastructure project, goes live
Pattern Energy Group (Pattern Energy), announced on June 18, 2026, that SunZia, the largest renewable energy infrastructure project in United States history, is fully operational. The SunZia project can generate and deliver more power than the Hoover Dam and supply affordable, reliable energy to the western U.S.
SunZia is an approximately 3,650-megawatt wind project and 550-mile high-voltage direct current transmission line, generating and delivering affordable, American-made energy from New Mexico to Arizona and to customers across the western grid. At full capacity, the project can deliver enough energy to power approximately one million American homes annually.
“SunZia proves that we can still build the consequential infrastructure this country needs,” said Hunter Armistead, CEO of Pattern Energy. “We did this the right way, we did it on time and on budget, in genuine partnership with the local communities and landowners who trusted us, with the environmental stewardship this unique landscape deserves and with the determination to see something through that many thought was too big and too complex to finish.”
